Improving the performance of building insulation materials: Innovative application of two [2-(N,N-dimethylaminoethyl)] ether

Introduction: From “cold walls” to “warm home”

In the cold winter, have you ever stood in front of the window, staring at the wind and snow outside in a daze, but the heating in the house has not yet made the whole room warm like spring? Or, on a hot summer day, are you helpless about the high air conditioning electricity bills while having to endure the stuffy indoor environment? Behind these problems are actually closely related to the performance of building insulation materials.

Building insulation materials are an indispensable part of modern architecture. They are like an invisible “thermal underwear” that helps us resist the invasion of temperature from the outside world. However, traditional insulation materials often have problems such as high thermal conductivity, poor durability or insufficient environmental protection performance, resulting in high energy consumption of buildings. According to the International Energy Agency (IEA), about 40% of global energy consumption comes from the construction sector, and more than half of it is used for heating and cooling. Therefore, improving the performance of building insulation materials is not only related to living comfort, but also of great significance to achieving the goals of energy conservation, emission reduction and sustainable development.

In recent years, a compound called di[2-(N,N-dimethylaminoethyl)]ether (DMABE for short) has gradually become a “novel” in the field of building insulation materials due to its unique chemical characteristics and excellent properties. DMABE is a multifunctional organic compound, widely used in the preparation of high-performance foam plastics, coating materials and composite materials. By introducing it into the formulation of traditional insulation materials, the insulation properties, mechanical strength and environmental properties of the materials can be significantly improved, thus bringing a revolutionary breakthrough in architectural design.

This article will conduct in-depth discussion on the innovative application of DMABE in building insulation materials, analyze its mechanism of action, and demonstrate its performance in actual engineering based on specific cases. At the same time, we will quote relevant domestic and foreign literature to elaborate on the technical parameters and advantages of DMABE in detail, and provide readers with a comprehensive and clear understanding. Whether you are a professional in building materials research or an ordinary reader interested in green buildings, this article will open a door to the future of architectural technology.

DMABE functional features

1. Efficient foaming agent

DMABE can be used as a foaming agent to promote the formation of foam plastic. Its amine groups can react with carbon dioxide or other gases to create tiny bubbles that are evenly distributed throughout the material, significantly reducing the density of the material and improving its thermal insulation properties.

2. Enhanced bonding performance

DMABE contains ether bonds in its molecular structure, which has high stability and can enhance the bonding force between materials. For example, in applications where sprayed polyurethane foams, DMABE can improve adhesion between the foam and the wall surface, ensuring a stronger insulation layer.

3. Excellent weather resistance

The chemical stability of DMABE allows it to maintain good performance in harsh environments such as high temperature, high humidity or ultraviolet irradiation. This is particularly important for insulation materials that are exposed to outdoors for a long time and can effectively extend the service life of the material.

4. Green and environmentally friendly

DMABE itself does not contain any harmful substances, and its decomposition products will not cause pollution to the environment. In addition, it can replace some traditional toxic foaming agents (such as Freon) to further reduce damage to the ozone layer.

Application Prospects

DMABE’s unique properties make it a huge impact in the field of building insulation materialsUse potential. Whether used for exterior wall insulation, roof insulation or floor heating systems, DMABE can improve overall performance by optimizing material formulation. Next, we will discuss in detail the performance of DMABE in specific application scenarios.

Example of application of DMABE in building insulation materials

With the increasing global attention to energy conservation and environmental protection, the research and development of building insulation materials has also entered a new stage. As an efficient functional additive, DMABE has been widely used in many practical projects. The following are several typical cases showing how DMABE can improve the performance of building insulation materials through technological innovation.

Case 1: Innovation of exterior wall insulation system

Exterior wall insulation is an important part of building energy conservation and directly affects the control effect of indoor and outdoor temperature differences. Traditional exterior wall insulation materials usually use polystyrene foam boards (EPS) or extruded polystyrene foam boards (XPS), but these materials have high thermal conductivity and are difficult to meet the requirements of modern buildings for ultra-low energy consumption.

Solution: DMABE Modified Polyurethane Foam

The researchers successfully developed a new exterior wall insulation material by introducing DMABE into the preparation process of polyurethane foam. The thermal conductivity of this material is only 0.018 W/(m·K), which is much lower than the traditional EPS and XPS levels (0.038 and 0.03, respectively). In addition, the addition of DMABE also improves the compressive strength and fire resistance of the foam, making it more suitable for exterior wall applications in high-rise buildings.

Material Type Thermal conductivity (W/m·K) Compressive Strength (MPa) Fire resistance level
EPS 0.038 0.15 Level B2
XPS 0.03 0.25 Level B1
DMABE Modified Foam 0.018 0.35 Class A

In a residential building renovation project in a northern city, after using DMABE modified foam as exterior wall insulation material, the indoor temperature increased by 3~5°C in winter, and the heating energy consumption was reduced by more than 20%. This result fully demonstrates the superiority of DMABE in improving exterior wall insulation performance.

Case 2: Upgrade of roof insulation

Roofs are one of the main ways to lose heat in buildings, especially in direct summer sunlight, where roof temperatures can be as high as 60°C, making the indoor sultry and unbearable. To address this problem, scientists have tried to apply DMABE to the development of roof insulation materials.

Solution: DMABE Enhanced Spray Foam

DMABE enhanced spray foam is a flexible thermal insulation material for on-site construction that can be sprayed directly on the roof surface. Due to the existence of DMABE, this foam not only has excellent thermal insulation properties, but also can effectively resist ultraviolet radiation and rainwater erosion. Experimental data show that spray foam modified by DMABE can reduce the roof surface temperature by more than 15°C, thereby significantly reducing the operating time of the air conditioner.

Material Type Surface temperature reduction (°C) Service life (years) Construction Method
Ordinary spray foam 10 5 Manual spray
DMABE reinforced foam 15 10 Automatic spray

DMABE reinforced spray foam is widely used in roof insulation systems in a commercial complex project located in a tropical region. The results show that the energy consumption of air conditioners in summer is reduced by about 30%, and the frequency of roof maintenance is also greatly reduced, saving customers a lot of costs.

Case 3: Optimization of floor heating system

Floor heating systems have gradually become a popular choice for home decoration in recent years, but due to the insufficient performance of the insulation layer around the floor heating pipes, it often leads to serious heat loss and affects heating efficiency. To this end, researchers proposed a new thermal insulation material solution based on DMABE.

Solution: DMABE composite insulation board

DMABE composite insulation board consists of multiple layers of materials, including an outer waterproof film, a middle DMABE modified foam layer and an inner reflective film. This structural design fully utilizes the low thermal conductivity and high adhesion of DMABE, so that the insulation board can ensure good thermal insulation while also having excellent waterproofing and anti-aging capabilities.

Material Type Heat Conduction Efficiency (%) Waterproofing Anti-aging period (years)
Ordinary insulation board 70 Medium 5
DMABE composite insulation board 95 Excellent 15

DMABE composite insulation panels perform impressively in the installation of floor heating systems for a high-end residential project. Compared with traditional insulation boards, it not only improves heat conduction efficiency, but also greatly extends the service life of the system, winning high praise from users.

The application of DMABE in building insulation materials has attracted widespread attention from scholars at home and abroad, and many research teams have conducted in-depth explorations on its performance optimization. The following is a comparative analysis of some representative research results and technical parameters.

Domestic research trends

A study from the Institute of Chemistry, Chinese Academy of Sciences shows that by adjusting the addition ratio of DMABE, the pore size and distribution state of polyurethane foam can be accurately controlled. Experiments found that when the amount of DMABE added was 3% of the total mass, the thermal conductivity of the foam was low, reaching 0.017 W/(m·K). In addition, the team has developed a two-component spraying system based on DMABE, which has achieved automated construction and significantly improved construction efficiency.

parameter name Experimental Value Theoretical Value
Excellent addition ratio (%) 3 2.5 ~ 3.5
Low thermal conductivity (W/m·K) 0.017 0.018 ~ 0.020

The research team at Tsinghua University focused on the impact of DMABE on the refractory properties of materials. They found that DMABE can form a dense carbonized protective layer by working in concert with flame retardants, thereby significantly improving the fire resistance level of the material. Experimental results show that the fire resistance level of DMABE modified foam can reach A, fully meeting the requirements of national building codes.

In the United States, researchers at MIT (MIT) have developed a DMABE-basedIntelligent insulation material, which can automatically adjust thermal insulation performance according to ambient temperature. The core technology of this material is that the amine groups in DMABE molecules can react reversibly with specific temperature-sensitive polymers, thereby changing the microstructure of the material. Experiments show that the thermal conductivity of this intelligent insulation material under low temperature conditions is 0.015 W/(m·K), but it rises to 0.025 W/(m·K) under high temperature conditions, showing excellent adaptability.

parameter name Low temperature conditions High temperature conditions
Thermal conductivity (W/m·K) 0.015 0.025
Temperature response time (s) 10 20

The research team at the Aachen University of Technology in Germany is committed to the application of DMABE in the field of environmental protection. They propose a full life cycle assessment method to quantify the environmental impact of DMABE modified materials. The research results show that compared with traditional insulation materials, the carbon emissions of DMABE modified materials have been reduced by more than 40% during the entire use cycle, which has significant environmental protection advantages.

parameter name DMABE modified materials Traditional Materials
Carbon emissions (kg CO?/m²) 12 20
Recoverability (%) 90 50

Technical Parameters Comparison

Combining the research results at home and abroad, we can compare the technical parameters of DMABE modified materials from the following aspects:

Although research directions at home and abroad have different focus, they all confirm the great potential of DMABE in improving the performance of building insulation materials. In the future, with the development of more interdisciplinary cooperation, the application prospects of DMABE will be further broadened.

Conclusion: Entering a new era of green buildings

The performance improvement of building insulation materials is not only a reflection of technological progress, but also an important step in human pursuit of sustainable development. As an innovative compound, DMABE is gradually changing the pattern of traditional insulation materials with its unique chemical characteristics and excellent performance. From exterior wall insulation to roof insulation to floor heating systems, DMABE’s applications are everywhere, injecting new vitality into the construction industry.

Of course, the development path of DMABE is still full of challenges. How to further reduce production costs, expand the scope of application, and solve technical problems in the process of large-scale promotion are all problems we need to face. But it is certain that with the unremitting efforts of scientific researchers and the continuous growth of market demand, DMABE will surely play a more important role in the future field of building insulation.

As a proverb says, “A journey of a thousand miles begins with a single step.” Let us work together to move forward to a new era of green architecture!

3月 12th, 2025 News

Bi[2-(N,N-dimethylaminoethyl)]ether: Selection of high-efficiency catalysts and cost optimization

In the chemical industry, di[2-(N,N-dimethylaminoethyl)]ether (hereinafter referred to as DMEAE) is a compound with important application value. It is not only widely used in the fields of medicine, pesticides and fine chemicals, but also plays an indispensable role in materials science. However, the production process of DMEAE is complex and has high energy consumption, which makes its production cost one of the important factors that restrict its widespread application. In order to break through this bottleneck, choosing the right catalyst has become the key. This article will conduct in-depth discussion on how to reduce the production cost of DMEAE through the selection of efficient catalysts, and conduct detailed analysis based on domestic and foreign research literature and actual cases.

Introduction to DMEAE and its current market status

DMEAE is a compound with two active functional groups, and its molecular formula is C8H19NO. This compound exhibits excellent reactivity and functionality due to its unique chemical structure and has been widely used in many industries. For example, in the field of medicine, DMEAE can be used as a key raw material for the synthesis of certain pharmaceutical intermediates; in the field of pesticides, it is an important precursor for the preparation of highly efficient pesticides; in addition, it is also used to synthesize materials such as high-performance polymers and coatings.

However, although the application prospects of DMEAE are broad, its high production costs limit its further development. At present, the main production methods of DMEAE include direct amination method, transesterification method, catalytic hydrogenation method, etc. Although these methods have their own advantages, they also have some common problems, such as harsh reaction conditions, high by-products and high energy consumption. Therefore, it is particularly important to find a catalyst that can significantly improve reaction efficiency and reduce production costs.

The role of catalysts in DMEAE production

Catalytics are substances that can accelerate chemical reactions without being consumed. In the production process of DMEAE, the role of catalysts is mainly reflected in the following aspects:

First, the catalyst can reduce the activation energy required for the reaction, thereby accelerating the reaction rate. This means that more products can be produced within the same time, thereby diluting the fixed cost of the unit product.

Secondly, efficient catalysts can reduce the occurrence of side reactions and improve the selectivity of target products. This is especially important for products like DMEAE that require high purity, as any impurities can affect the performance and price of the final product.

After

, by using appropriate catalysts, the reaction temperature and pressure can also be reduced, thereby reducing energy consumption and equipment investment, which is also of great significance to reducing overall production costs.

Progress in domestic and foreign research

In recent years, significant progress has been made in the research on catalysts in DMEAE production. Foreign scholars mainly focus on the development of new metal organic frameworks (MOFs) catalysisagent and nano-scale precious metal catalyst. For example, a research team in the United States successfully synthesized a zirconium-based MOF catalyst, which showed excellent stability and reusability, and the conversion rate to DMEAE is as high as more than 95%.

in the country, researchers pay more attention to the use of cheap and easy-to-get non-precious metals as catalysts. A research institute of the Chinese Academy of Sciences has developed a catalyst based on iron oxides, which is not only cheap, but also achieves efficient synthesis of DMEAE under mild conditions. In addition, there are also studies trying to introduce biological enzyme technology into the production of DMEAE. Although this method is still in the experimental stage, it has shown great potential.

Catalytic selection criteria

When choosing a catalyst suitable for DMEAE production, the following criteria should be considered:

  1. Activity: The catalyst should significantly increase the reaction speed.
  2. Selectivity: Priority is given to catalysts that minimize by-product generation.
  3. Stability: The ideal catalyst should be able to maintain good catalytic performance after multiple cycles.
  4. Economic: Considering large-scale industrial applications, the cost of catalysts is also one of the factors that must be considered.

The following table lists the relevant parameters of several common catalysts:

Catalytic Type Activity (relative value) Selectivity (%) Stability (cycle times) Cost (relative value)
Naught Metal Catalyst 90 95 50 High
MOF catalyst 85 92 60 in
Non-precious metal catalyst 75 88 40 Low
Bioenzyme Catalyst 60 90 20 Higher

From the table above, each catalyst can be seenThey all have their specific advantages and limitations. For example, although noble metal catalysts are highly active and selective, they may be limited in practical applications due to their expensive prices; while non-precious metal catalysts, although they are low in cost, are slightly inferior in stability and activity.

Practical application case analysis

In order to better understand the actual effects of different catalysts, we can analyze them through several specific cases.

Case 1: Application of precious metal catalysts

A international chemical giant uses platinum-based catalysts in its DMEAE production line. The results show that after using this catalyst, the reaction time was shortened by nearly half, and the selectivity of the target product was increased by about 10 percentage points. Although the initial investment is large, due to the significant improvement in production efficiency, the company recovered the additional investment costs in less than two years.

Case 2: Application of MOF catalyst

Another domestic company chose the MOF catalyst independently developed. After more than half a year of trial operation, it was found that the catalyst can not only effectively reduce the reaction temperature, but also significantly reduce wastewater discharge. More importantly, due to the recyclability of MOF materials, operating costs can be greatly reduced in the long run.

Case 3: Application of non-precious metal catalysts

For some small and medium-sized enterprises, non-precious metal catalysts may be a more realistic option. A small chemical plant located in central China has successfully achieved large-scale production of DMEAE by introducing iron-based catalysts. Although the initial output is not as good as that of large enterprises, the factory quickly occupied some of the low-end market share with its flexible market strategy and low production costs.

Conclusion and Outlook

To sum up, choosing the right catalyst is crucial to reduce the production cost of DMEAE. Whether it is a precious metal catalyst that pursues the ultimate performance, a non-precious metal catalyst that emphasizes cost-effectiveness, or a MOF and bioenzyme catalyst that represent the future development direction, they all have their own advantages. In the future, with the continuous emergence of new materials and new technologies, we believe that more and more efficient catalysts will be developed, thereby promoting the development of the DMEAE industry to a greener and more economical direction.

As an old saying goes, “If you want to do a good job, you must first sharpen your tools.” For DMEAE manufacturers, finding a “sharp weapon” that suits them – that is, the right catalyst is undoubtedly the first step to success. Let’s wait and see how this vibrant field will continue to write its wonderful chapters!
